A student reacted 0.500 g of Pb(NO.)2 with 0.750 g of KI according to the reaction, Pb(NO.b (aq) + 2 KI (aq)- → Pbb (s) +2 KNO: (aq) How many moles of Pb(NO.)2 were used? mol of Pb(NO) b) How many moles of KI were used? mol of KI c) How many moles of PbL would form, based on mol of Pbb the moles of Pb(N0) used? d) How many moles of Pbl would form, based on mol of Pbl the moles of KI used? e) Which is the limiting reactant? What is the theoretical yiekd of PbL in grams? 主 g of PbL g) If the student obtained 0.583 grams of PbL product after collecting it by fihration and dry ing it, what was the percent yield of Pbl obtained? 2.
